1.arm-eabi-addr2line (直接根据*。so崩溃的地址找到函数的行)
../toolchain/arm-eabi-4.4.0/bin/arm-eabi-addr2line -f -e out/target/product/m801/symbols/system/lib/libstagefright.so 0005e524（崩溃的地址）
2.arm-eabi-objdump (直接反编译*。so)
../toolchain/arm-eabi-4.4.0/bin/arm-eabi-objdump -S out/target/product/m801/symbols/system/lib/libstagefright.so > obj.txt
3.arm-eabi-gdb
../toolchain/arm-eabi-4.4.0/bin/arm-eabi-gdb out/target/product/m801/symbols/system/lib/libstagefright.so
